The answer is because the admissions office is only the publisher of transfer information, and the actual decision is not in their hands. Generally speaking, the transfer quota is determined by the college according to the actual recruitment situation, and then reported to the school for approval, and the school makes a decision. Therefore, the admissions office may know whether there are any transfer places, but generally it doesn't know how many.
Precautions for dispensing
1, some schools have pre-adjustment before the formal adjustment. Early adjustment is very important. Some schools will also hang information such as transfer majors and quotas in the transfer system when they are officially transferred, but that is for candidates who have been pre-transferred and admitted to the second interview, in order to let them go through the formalities and go through the process, not to let you fill in the volunteers at all.
2. Be sure to call the research and recruitment office or college of the school before filling in the volunteer, and ask if there are any places. Because some schools, especially better schools like 2 1 1, should be full of places, but they have not been excluded from the adjustment system.
When you make a phone call, ask whatever you want. Don't be embarrassed to ask. Once you hang up, it will probably be difficult to get through again. I think everyone knows that the difficulty factor of making a phone call during the adjustment period is not generally high.
